EDF Extended Supply Rates – Effective 1st November 2025
EDF Extended Supply Out of Contract Rates 2025
Your business energy rates explained
If your fixed-rate contract with EDF has ended and you haven't switched, you're on their Extended Supply Out of Contract Rates. Rates vary by location and meter type. Most businesses save up to 70% by locking into fixed rates.
What This Means for Your Business
If your fixed-rate contract with EDF has ended and you haven't switched to a new supplier or plan, you're now on their Standard Variable Rate (Extended Supply). This means your energy rates can change with 30 days' notice and aren't locked in like a fixed contract. Most businesses save up to 70% by switching to fixed rates at the right time.
💡 EDF Extended Supply Rates (Non Half-Hourly)
| Energy Type / Meter Type | Fixed Daily Charge Range | Unit Rate |
|---|---|---|
| ⚡ Electricity (Profile 01-04, NHH) | 325–507p per day (varies by DNO/TCR band)* | 44.48p per kWh |
| ⚡ Electricity (Profile 05-08, NHH) | 643–721p per day (varies by DNO/TCR band)* | 44.48p per kWh |
| 🔥 Gas (Standard Meter) | 1877.10p per day | 11.621p per kWh |
*Fixed Daily Charges vary based on your DNO (Distribution Network Operator) region and TCR (Targeted Charging Review) banding. All prices exclude VAT and Climate Change Levy (CCL). This table shows Non Half-Hourly (NHH) rates only. Half-Hourly rates are significantly more complex and vary further by voltage level, capacity, and time-of-use periods.
Non Half-Hourly (NHH) Rates
NHH meters are standard for most small-to-medium businesses. The unit rate is fixed at 44.48p/kWh, but the Fixed Daily Charge varies based on your location (DNO region) and TCR banding.
| Profile Class | Unit Rate (p/kWh) | Fixed Daily Charge Range (p/day) | Note |
|---|---|---|---|
| 01-04 (Standard SME) | 44.48p | 325–507p | Most common for small businesses |
| 05-08 (Medium Business) | 44.48p | 643–721p | For businesses with higher demand |
| Unmetered Supply | 44.48p | 492.01p | Fixed daily charge (not DNO-dependent) |
What Affects Your Fixed Daily Charge?
DNO Region: Your location determines which distribution network operator supplies you. There are 14 DNO regions in Great Britain, each with different charges (Eastern, London, North West, Yorkshire, etc.).
TCR Band: Your TCR band (No Residual, Band 1, 2, 3, or 4) affects standing charges. Most small businesses fall into "No Residual" or "Band 1". Your supplier will determine your banding based on your consumption profile.
Half-Hourly (HH) Rates — More Complex
EDF's Half-Hourly rates are significantly more complex. They include:
- Multiple voltage levels: Low Voltage, Low Voltage Substation, High Voltage, Extra High Voltage
- Time-of-use rates: Different prices for "All Other Times", "Nov & Feb Peak", "Night", "Winter Weekday"
- Capacity charges: p/kVA/day based on your agreed import capacity
- TCR bands: Further pricing variations by banding (Non Residual, Band 1, 2, 3, 4)
- Regional variations: All rates vary by your 14 DNO regions

📋 Key Takeaways
- Your rates can change — they're not locked in and can shift with 30 days' notice
- You're paying premium prices — standard variable rates are typically 10-30% higher than fixed deals
- Electricity at 44.48p/kWh is significant — well above typical fixed-rate market prices
- VAT and CCL apply on top — these vary by region and government rates
- Most businesses don't realise the cost — locking in fixed rates could save thousands annually
💰 How Much Could You Be Overpaying?
Extended Supply rates with EDF are premium prices with no price protection. Depending on your consumption, location, meter type, and the current market, you could be paying up to 70% more than a fixed-rate deal.
For example: A business on EDF's Extended Supply could spend an extra £3,000–£8,000+ annually compared to locking a fixed rate today. The exact amount depends on your annual consumption (kWh), gas vs electricity split, location (DNO charges), and current wholesale rates.
You're Paying More Than Necessary
Standard Variable Rates are designed to increase over time — that's how suppliers protect themselves against market swings. If you've been on EDF's Extended Supply for more than a few months, you're almost certainly paying 20-50% more than businesses with comparable fixed-rate contracts. Rates can change with 30 days' notice, so the longer you wait, the more expensive it becomes.

Get Your Free Quote❌ Why Being on Standard Variable Rates Costs Thousands
When your EDF fixed-term contract ends, you don't continue on the same rates. Instead, you're automatically rolled onto their Standard Variable Rate — which is significantly more expensive than current market fixed-rate deals.
No commitment = no incentive
Without a contract locking you in, they have no reason to offer competitive rates. They know most businesses won't act immediately or won't realise how much they're overpaying.
Customer inertia works in their favour
They bank on businesses staying put, especially those satisfied with the service or too busy to switch.
Rates can change at any time with 30 days' notice
Your standard variable rates aren't fixed and can increase based on market conditions — often with minimal warning.
For every month you wait, money drains away
Delaying 3–6 months on Extended Supply can cost £500–£2,000+ more than if you'd locked in a fixed deal today.

❓ Frequently Asked Questions
Check your latest EDF bill for the tariff name. If it says "Extended Supply" or doesn't mention a fixed contract end date, you're on their Extended Supply out of contract rates. You can also log into your EDF business account online. If your contract ended and you didn't actively choose a new one, you've been automatically moved to Extended Supply rates. Contact EDF on 0845 366 3664 if you're unsure.
Absolutely! Being on Extended Supply rates means you're free to switch at any time with no exit fees or penalties. In fact, this is the perfect time to switch because you're not locked in. The switching process typically takes 2–5 days, and your energy supply won't be interrupted. Your electricity and gas flows through the same National Grid system, so you'll continue receiving power without any break. EDF will handle the transition smoothly.
Most businesses save between 15-30% when switching from standard variable rates to a competitive fixed contract. In exceptional cases, savings can reach 50-70% depending on your consumption profile, meter type, and location. For a typical business, this translates to £2,000–£8,000+ per year. The exact savings depend on your usage, location, meter type, and current market rates. Get a live quote to see your personalised savings.
Yes. Extended Supply rates are variable and can change with notice. There's no price protection, so EDF can increase your rates whenever they choose (within Ofgem regulations). This is why staying on Extended Supply long-term is risky — your costs could keep climbing without warning. Fixing a contract now removes this uncertainty and locks your rates.
No, your energy supply is never interrupted when switching suppliers. The switch happens behind the scenes through the National Grid system. You'll continue receiving electricity and gas without any disruption. The only changes you'll notice are lower bills and correspondence from your new supplier instead of EDF. You'll receive final bills and meter readings as part of the handover process.
We don't charge you anything. Our service is completely free. We're paid a commission by energy suppliers, which is fully declared in your contract paperwork. Here's why using us makes sense: we have access to wholesale base rates that suppliers don't offer when you contact them directly. This means we can often secure better deals than you'd get going to suppliers yourself — even with our commission included. Plus, we save you the time and hassle of contacting dozens of suppliers individually.
